Reply to "Holley Sniper EFI install"

Hi Everyone,

I'm late to the party, but also in the middle of installing a Holley Sniper Stealth EFI system.  I bought it almost 2 years ago, but life has gotten in the way of installing it (death in the family, the birth of 2 grandchildren, the marriage of my youngest daughter, and the move of my son from Dunedin, FL to Enumclaw, WA).  In any case, I'm working on it now.  I've heard how great the Sniper2 is, but I don't see that the "stealth" model has a version 2.  Does anyone know?  I'll call Holley tomorrow morning to find out, and see if they'll exchange my new in the box Sniper Stealth for the new version 2, if it exists in the Stealth model.

I'm installing the stealth version because I want to use the stock air cleaner, which doesn't fit on the standard Sniper throttle body.  I also purchased the entire Holley ecosystem so all the connections should be plug and play. Following is what I purchased:

• Holley Hyperspark CDI box
• Holley Hyperspark coil
• Holley Dual Dual Sync Distributor
  • I originally purchased the Hyperspark Distributor, but the damn thing was 4" taller than both the stock distributor and my Mallory Unilite distributor, so it would never fit under the engine screen.
  • The dual sync distributor is low profile, but it's for a 351W, so I changed out the distributor gear for a Cleveland gear compatible with my roller cam.
• 3/8" copper-nickel tubing to fab new fuel lines.
• Walbro #GSL392 external fuel pump, mounted to frame rail under the gas tank.
• Bosch #17025 O2 sensor
• Wix #33033 pre-filter

• Wix #33482 post-filter

Now on to my questions...

1. The Sniper Stealth requires an external fuel regulator with bypass for the return line.  I was thinking of mounting it high on the firewall adjacent to the gas tank as there's plenty of room there.  If you installed the Stealth version, where did you mount the external regulator? 
2. What wire in the stock harness did you use for your 'switched 12v' source?
3. Did you run a dedicated wire all the way to the front trunk to connect directly to the battery as the instructions insist, or merely connected to the BATT terminal side of the starter solenoid where the heavy gauge cable comes directly from the battery?

Thanks for any info and pics, and/or additional part numbers for various fuel fittings, etc. that I will need.
